A1R confocal with spectral detector

Resonant scanning - The A1R+ confocal has a hybrid scan-head
that incorporates both a resonant and a galvonometer scanner. The
resonant scanner is capable of high speed image capture at rates ranging
from 30 frames per second (512 x 512 pixels) to 420 frames per second
(512 x 32 pixels), while the galvonometer scanner can be used for high
resolution imaging. They can be combined for simultaneous imaging and
photobleaching or stimulation experiments.

GaAsP detectors - The A1R+ is equipped with two normal PMTs
and two high-sensitivty GaAsP detectors (green and red channels)
enabling visualisation of even very weak signals.
